A couple weeks ago I got my first handgun. For $200 I got a CZ-52, 30rds, dies, 2 mags, and a holster. It also came with a new Wolf recoil spring and aftermarket firing pin. I love the feel of this gun and the looks.
Very nice, and seems that you got a decent deal.

The '52 was my first handgun too, I
used to consider myself more a rifle person...

There are a number of after-market firing pins for the '52, so you may want to double-check the model/manufacturer. Depending on the style/manufacturer of the firing pin,
do not trust the de-cocker. Some people will likely tell you that
anyway, but the odds of the de-cocker not working are only increased with certain after-market firing pins.
